    CHK-NON_F, Non-Insertable Check Standard SMA (f-f)

    The TA431 CHK-NON-F is a check standard for use with a non-insertable DUT, with a female to female port that can be used to validate the accuracy of a network analysis test setup and its calibration before and during or after measurements are made. Akin to the Beatty line, each check standard is a short length of mismatched line (75 mm of 25 O) with a predictable, smooth and stable mismatch and transmission characteristic that spans the frequency range of the PicoVNA 106. These devices validate system measurement accuracy in the presence of high and varying mismatch and thus present a demanding validation on which to base confidence in a setup.

    A comparison utility is provided in the PicoVNA 2 software to evaluate the comparison against a combination of specified measurement uncertainties for the device, test leads and instrument. Each check standard is supplied with Touchstone measurement data on USB memory. The data is traceable via PC3.5 standards to national standards. The supplied Touchstone measurement data is compatible with and can be used to manually validate a measurement of any manufacturer’s VNA.
